This folder is NOT a git submodule.

Files in this folder are extracted from the same SQLite release package. The
release number is noted in VERSION. Basically only lemon.c and lempar.c are
used for this project, which makes it not worth syncing a 106Mb git repo.

To compile the lemon parser, enter

```
cc lemon.c -o lemon
```

This is taken care of by the Makefile in the `./src/codec` directory, which
places the executable in `./bin`.
